SoundTraxx DSD-150/DSX Technical Reference - Manual (Page 3)

Upon completion of a paged mode operation, the DSD will reset the page register to 01.
The address query instruction is not supported by the DSD.
Miscellaneous Operating Notes
Consist operation is enabled whenever the consist address (CV 19, bits 0:6) is loaded with a non-zero value. Per the
NMRA standard, when the consist address is enabled, the DSD will no longer parse speed/direction packets sent to
its primary address. Additionally, the DSD will ignore long form CV access instructions sent to its consist address.
Because the DSD instruction parser assigns a higher priority to the consist address, this can cause unexpected
behavior under certain conditions:
When the DSD is set up for 14 speed step mode with the consist address active, the DSD outputs will no longer
respond to FL function commands sent to the primary address. This may be remedied by using a different speed
step mode or enabling FL consist functions (see CV 22).
If the consist address is set to the same value as the primary address, the DSD will no longer process long form
operations mode CV access instructions sent to the primary address. As a result, the user will be required to use
service mode CV access instructions to clear the consist address. If the extended address is enabled (see CV 29),
this will not be a problem.
Analog Mode Operation
The DSD does
not support Analog Mode operation and will remain inoperative when placed on a conventional DC
track.
CVs Support
The following table lists all CVs used by the DSD. Details regarding each CV can be found on subsequent pages.
